Thanks for pointing that out. I thought it was some sort of variation on an E-ink display because of the black and white limitation. Nothing about transflective tech limits it from full color other than price. I guess that leads me to an evolution of my question: Why are no* tablets using full color transflective displays?

*I did find the HannsNote2 [1] does, but it only came out last year, and this tech has been around for donkey's years.
